Ditto on that. Also makes it possible AdoredTV's leak is wrong on the bus width of the 2060 as well.
If the 2060 retains the 192-bit bus with 14 Gbps GDDR6, we're looking at a 336 GB/s bandwidth theoretically giving ~41 MH/s on Ethash. If they sell the 2060 at ~$300 and it does around 75W when mining, it would compare favorably against a ~$1300 bitmain E3.
